May 2019 - May 2019

RESEARCH GEOPHYSICIST, TOTAL, ABERDEEN, UK

March 2017 - July 2017

Topic: Time-shifts vs. Offset and offset-dependent dilation factors

The aim of the project was to analyse the importance of time-shifts vs. Offset. In addition, this will enable the various dilation factor models (R - Factors), which link to geomechanics, to be evaluated.
- Construct a 2D model of the subsurface of the field.
- Perform a ray tracing seismic modelling both for base and monitor surveys.
- Invert for modelled time-shifts using post-stack approach.
- Apply the various dilation factor models
- Link the results of the process performed in number 2-3 with the geomechanical simulation results.
- Calculate 4D time-shifts both with the modelled and real data.

DJANGO WEB DEVELOPER, UCL - SEISMOLAB, LONDON, UK

May 2015 - September 2015

Topic: Website for SGLOBE rani model based on Django Framework

The aims and goals of the project were set using the requirements as stated by the client.
- Perform a background research in seismic tomography and other websites for promoting
seismology.
- Compare the advantages and disadvantages of PHP and Django for creating a
dynamic website.
- Develop MATLAB scripts to produce quantitative comparisons between models.
- Learn Generic Mapping Tools (GMT) to produce PostScript tomographic images.
- Become familiar with HTML, CSS and JavaScript to build the front-end interface
of the website.
- Learn Python, Django and MySQL to create a website serving the needs of the
project.
- Engage with Linux and C shell commands to use GMT and Django.
- Explore the options on Amazon Web Services to deploy the website.
- Visualise and analyse the SGLOBE-rani model.
- Generate regional and global tomographic images using GMT in real-time.
- Provide information about data, method and references of the SGLOBE-rani model.
- Deliver a website ready to be published.
- Present the results of the SGLOBE-rani model.

ANDROID SOFTWARE DEVELOPER, UNIVERSITY OF CYPRUS, NICOSIA, CYPRUS

- Introduced to java and android application development by working as a part of a group to implement an android application called Social Activities.
